IUBMB Enzyme Nomenclature


Accepted name: arginyltransferase

Reaction: L-arginyl-tRNAArg + protein = tRNAArg + L-arginyl-[protein]

Other name(s): arginine transferase; arginyl-transfer ribonucleate-protein aminoacyltransferase; arginyl-transfer ribonucleate-protein transferase; arginyl-tRNA protein transferase; L-arginyl-tRNA:protein arginyltransferase

Systematic name: L-arginyl-tRNAArg:protein arginyltransferase

Comments: Requires 2-sulfanylethan-1-ol (2-mercaptoethanol) and a univalent cation. Peptides and proteins containing an N-terminal glutamate, aspartate or cystine residue can act as acceptors.
